Abstract

Cyano-organophosphorus compounds react by a metathesis reaction in a liquid medium with tetravalent metal ions yielding layered crystalline to amorphous inorganic polymers having the empirical formula M(O.sub.3 PRCN).sub.2 or M(O.sub.3 PORCN).sub.2 where M is a tetravalent metal and R is a an organic group covalently bonded to phosphorus and the terminal cyano group. One use for the compounds is as ion complexers.
